DATA
Timing Waveform of Write with Port-to-Port Read and BUSY
NOTES:
1. To ensure that the earlier of the two ports wins. t
2. CE
3. OE = V
4. All timing is the same for the left and right ports. Port 'A' may be either the left or right port. Port "B" is opposite from port "A".
Timing Waveform of Write with BUSY
NOTES:
1. t
2. BUSY is asserted on port "B" blocking R/W
3. All timing is the same for the left and right ports. Port "A" may be either the left or right port. Port "B" is oppsite from port "A".
